What factors do you consider to help guide treatment for patients with high grade large cell neuroendocrine cancers of the lung?
High-grade large cell neuroendocrine carcinomas make up a small and aggressive subset of lung cancers that histologically and regarding treatment responsiveness share features with both small and non-small cell carcinomas. These shared features have been borne out in recent sequencing studies of thi...
What is your approach to managing hyperkalemia secondary to respiratory acidosis?
Since hyperkalemia in respiratory acidosis is due to transcellular shift, therapy should be directed at treating the underlying respiratory acidosis. Correction of the hypercarbia should lead to resolution of the hyperkalemia. In severe hyperkalemia due to respiratory acidosis that is not easily rev...
Are there any biomarkers, imaging, or other clinical information that can be used to better choose effective therapies for super refractory status epilepticus?
SRSE is a syndrome not a diagnosis. The key determination is if this is immune-mediated, infectious, structural, metabolic, genetic, or drug/toxic-induced. For example, if the lumbar puncture shows significant pleocytosis, in the presence of flare changes in the medial temporal lobes, especially in ...
What is your approach to volume resuscitation in patients who are third spacing fluids?
In patients with significant third-spacing (e.g., due to capillary leak in sepsis, severe pancreatitis, hypoalbuminemia, etc), we prefer balanced crystalloids (e.g., Lactated Ringer’s) as the first-line fluid for initial resuscitation in hypovolemic or septic shock with third-spacing. Typical initia...
Do you obtain routine blood cultures in a non-immunocompromised patient with community-acquired pneumonia who does not meet criteria for severe CAP?
Fabre et al., PMID 31942949, categorizes "non-severe community-acquired pneumonia" as low yield for bacteremia and therefore less critical and potentially wasteful/poor stewardship to obtain blood cultures, however do note that severe community-acquired pneumonia (CAP) falls into a moderate pre-test...
How do you decide when to initiate antibiotics for superimposed bacterial pneumonia in patients with influenza?
Antibiotic therapy should not be routinely prescribed for patients with influenza and should instead be reserved for those with a specific clinical concern for secondary bacterial pneumonia. This diagnosis is best identified by clinical trajectory. Key triggers include initial improvement followed b...
In patients presenting with disabling acute ischemic stroke symptoms early in the therapeutic window, would you consider anticoagulation reversal to enable administration of intravenous thrombolytics?
In short, 'no'. For patients who have a large vessel occlusion, there is the option of proceeding directly to EVT without thrombolysis. We know from the direct EVT trials that although concurrent or sequential thrombolytic drug treatment followed by EVT is better, it is better only by a small amount...
How do you approach tapering high dose continuous infusions for status epilepticus in patients experiencing serious medication-related toxicity?
The short answer is as quickly as possible. How you do it will somewhat depend on the need for ongoing continuous infusion of a sedative for treatment of status epilepticus. Probably the most severe toxicity syndrome is Propofol-Related Infusion Syndrome (PRIS), which if not recognized early, can le...
What is the recommended fungal workup in an immunocompromised patient after 5 days of persistent fever?
For any patient with fevers, I focus significantly on any symptoms that a patient might have, like headache, diarrhea, and sinus symptoms, and work up a differential diagnosis based on possible pathogens in this area. If I am not finding anything, I would obtain a CT chest/abd/pelvis, as both invasi...
Would you initiate antifibrotic therapy in a patient with CTD-ILD experiencing worsening symptoms and declining lung function, despite no clear evidence of fibrosis on CT scans?
If the predominant findings on CT were ground glass opacities and/or nodules without any evidence of fibrosis on CT, I would not start with an antifibrotic and, instead, would start with immunosuppression as a first-line agent. Based on the American College of Rheumatology (ACR) and American Thoraci...
